Quarterly statistics from the Financial Ombudsman Service (FOS) has revealed a 10% drop in upheld complaints in private medical insurance (PMI) and dental insurance.
The FOS believes little change is likely in annual figures for PMI and dental insurance however.
The figures showed there was only one less enquiry about PMI and dental claims between the last quarter, July-September and the previous April-June quarter, there was a fall in the number of new cases, from 197 to 188.
A spokesperson for FOS said: "To get an idea of the bigger picture for medical and dental insurance complaints is to look at the figures on a year on year basis. This provides more context as there are a larger number of complaints used to calculate the uphold rate on.
"In FY2012/13 the uphold rate was 38%, in FY 2013/14 it was 40% and in the six months of this year the rate is currently 37% so despite the fluctuations between Q1 & Q2 this year, the figure is actually remains pretty consistent."
